Go in early and try to snag a step van. Take a piece of paper for each route, write down the North/South addresses in one column (streets) and East/West addresses in the other (avenues).
Make sure to load your truck properly, prioritize signature items and leave CMB parcels behind. Focus on townhouses and apartments. If you're space limited then consider focusing on the smaller stuff and leave a few bigger ones behind (the carrier will probably card those on Monday).
Safedrop *everything* that's safe to do so. Most people are home, they're just not expecting a knock at the door. I usually just knock, drop, run and give them a wave/pointing motion as I'm backing out of their driveway.
I usually hit about 120-140 parcels in a shift; they want to see at least 15 per hour. Don't stress out if you're not hitting those numbers.
AND TAKE YOUR BREAKS because they won't let you sign out early.
edit: And don't forget to cut off early to give yourself time to drop off your carded parcels at the RPO. Most depots do not have an end of day run and many RPO's close at 4 or earlier on the weekend.
